  • Page 74: Figure 3-9: Acquisition: Input Analog Signal, Sample, And Digitize

    The two general methods of sampling are real-time and equivalent-time. The TDS 600B Oscilloscopes use only real-time sampling; the TDS 500B and TDS 700A Oscilloscopes use both real- and equivalent-time sampling. In real-time sampling, the oscilloscope digitizes all the points it acquires after one trigger event (see Figure 3–11).
  • Page 75: Figure 3-12: Equivalent-Time Sampling

    Acquiring and Displaying Waveforms Equivalent-Time Sampling A TDS 500B or TDS 700A model oscilloscope (the TDS 600B use only real time sampling) uses equivalent time sampling to extend its sample rate over its real-time maximum sampling rate, but only under two conditions: You must have turned equivalent-time on in the Acquisition menu.

  • Page 77: Table 3-2: How Interleaving Affects Sample Rate

    The Acquisition Modes All oscilloscopes in this manual support the following four acquisition modes: Sample, Envelope, Average, and Peak Detect. TDS 500 B and TDS 700A Oscilloscopes also support Hi Res. Keep in mind which modes apply to your model oscilloscope as you read the following descriptions.

  • Page 190 Status and event reporting To simplify the development of GPIB systems, include instruments that use Tektronix defined codes and formats for messages that travel over the GPIB. Each device that follows these codes and formats, such as this oscilloscope, supports standard commands. Use of instruments that support these commands can greatly simplify development of GPIB systems.
  • Page 191 Obtain the Proper Interconnect Cabling. To connect the oscilloscope to a GPIB network, obtain at least one GPIB cable. Connecting two GPIB devices requires an IEEE Std 488.1-1987 GPIB cable (available from Tektronix, part number 012-0991-00). The standard GPIB cable connects to a 24-pin GPIB connector located on the rear panel of the oscilloscope.
